New to the forum here! I have a question for you guys, maybe you will be able to help me.
I have a 2007 Chevy Equinox AWD. Last february my intake manifold gasket went bad and so my head gasket at the same time. Was replaced at my best friend’s shop. Did a bit myself and he did his part as well. In April I started to have a rough idle and misfire. The computer thrown a P0301 code. Replaced the spark plug and the problem went away. Problem came back in November. Tried to replace the spark plug wires and did nothing. Replaced the spark plus no1 again and problem went away.
Guest what, yesterday problem came again. Same rough idle, same P0301. I’m a little bit worried about what can cause the spark plug to go bad again.
(sorry if my english is not the best, french speaker here 😀 )
